To all 10. mm it may concern Be it known that I, ELIJAH MCCOY, a citizen of the United States of America, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to lubricators of that type particularly adapted for use on locomotives, and for feeding the oil into the cylinders against high pressure steam.

The invention consists in certain features of construction as will be more fully hereinafter set forth.

In the drawings, Figure 1 is a diagrammatic side elevation of a locomotive to which the lubricator is attached; Fig. 2 is an end elevation thereof; Fig. 3 is a dia grammatic perspective view, illustrating the various pipe connections of the lubricator;

Fig. 4 is atop plan view; Fig. 5 is an en larged horizontal section of a portion of Fig. 4; Fig. 6 is a sectional elevation of the lubricator, viewed as in Fig. 2; Fig. 7 is a section through the upper portion of the condenser; Fig. 8 is a section through the conduit for replenishing water to the sightfeed and supplying steam to the heater; and Fig. 9 is a cross section through a form of locomotive cylinder and steam chest, illustrating the pipe connections thereto.

A is an oil cup, B is a. condenser connected with said cup for feeding the oil therefrom by hydrostatic pressure, and C is a pump for receiving the oil from said cup and mechanically propelling it to the parts to be lubricated. These parts are preferably assembled in fixed relation to each other and are adapted to be secured to a locomotive boiler D, in convenientposition, as by means of the bracket E.

F F are the tallow pipes through which the oil is forced by the pump 0 and which lead to the cylinders G of the locomotive.

The steam for supplying the condenser E and. for operating the pump 0 is supplied from any suitable source, as for instance the steam box H on the locomotive boiler, to which all the various steam conduits are usually connected.

J and is controlled by the single valve I, so i that when the latter is closed, the whole apparatus is thrown out of action.

In addition to supplying oil to the cylinders of the locomotive, the lubricator is also provided with an attachment for lubricating the air brake cylinder; and further with a conduit by which the cylinder of the operating pump C may also be lubricated. The

various parts of the apparatus are prefer- I ably assembled in the relation illustrated in. Figs. 1, 2, and 3, in which the oil cup A is directly connected to the supporting bracket E, and a laterally projecting arm E from said bracket supports the oil pump C at one side of the cup. The condenser E isarranged in rear of the cup, and two sight feeds K, K, the one for the locomotive cylinders and the other for the air brake, are arranged on opposite sides of the cup A, as shown.

Hydrostatic fec(Z.All the various conduits for receiving oil are supplied in the first place from the cup A by hydrostatic feed. To this end, the condenser B is connected to a pipe (4 leading downward through the cup A into a central well I) atthe bottom thereof, the latter being preferably formed in a detachable plug 6.

c and (Z are pipes leading from the upper portion of the chamber within the oil cup, downward and outward respectively to the sight feeds K, K. e is a feed pipe, connected with a conduit 6 which forms a bypass around the sight feed K and connects with the discharge conduit therefrom, being designed for use in emergency, as when the glass of the sight feed breaks. To all of these oil pipes 0, (Z and 6, oil is fed by the hydrostatic pressure of the water column in the condenser B, as is usual in lubricators of this type.

After passing into the tallow pipes F, F, the feeding of the oil is controlled by automatic valves F the opening of which is resisted by a steam pressure equal to that in the steam cylinder of the pump C. The specific construction of these valves F forms no part of the presentinvention, and is therefore not illustrated. In function, the valves F act as governors for securing the uniform operation of the pump under varying steam pressures, and also under varying back pressure pulsations in the locomotive cylinders. The steam operating upon the valves F is supplied through a conduit P preferably attaching to the top of the condenser B and branching at P to lead to the two valves. As shown, the pipe P is mechanically tied to the conduit J, which supplies steam to the cylinder of the pump G by a yoke P and this fitting, as illustrated in Fig. l, is preferably formed integral with an elbow P forming a bend in the pipe P, but the pipes P and J have no steam connection through this fitting.

The oil supplied to the cylinder 2' of the pump 0 is cont-rolled by the sight feed K through a valve K controlling the oil discharge nozzle K connecting the pipe 0. After passing through the water in the transparent tube K the oil is delivered into a conduit K leading to the pump C. The

by-pass 0 also connects with the conduit K K of the sight feed is attached.

and this is controlled by the valve 6 which is normally closed, so that all of the oil fed to the pump passes by way of the sight-feed.

Heater and water ieplenz'shcr for sight fee(Z.To maintain the proper feeding of the oil, it is desirable to prevent it from becoming too cold, and to this end a heater is provided, which may be regulated to keep the oil at the desired temperature. It is also necessary to provide means for replenishing the water in the transparent tube K of the sight feed. I have therefore provided a steam conduit L, which preferably leads from the top of the condenser B and furnishes steam both for the heater and for replenishing the sight feed, the construc tion being as follows :L is the fitting to which the upper end of the transparent tube This fitting is provided with a nipple g engaging a threaded aperture in the cup A, and L is a radiator tube connected into this nipple and extending across the cup near the upper end thereof. The tub-e L communicates through a passage 9 in the fitting L with a laterally projecting arm g of the fitting, in which is arranged the valve L The conduit L is also connected to this arm 9 and the passage of steam through the conduit is controlled by valve L The valve is, however, provided with a restricted port 1", which is open when the valve is seated, so that there is a constant communication through the port between the conduit L and the radiator tube L Within the conduit L is arranged a further restriction, which operates to limit the amount of steam fed, and also to prevent the clogging of the ports by sediment carried by the steam. As shown in Figs. 7, 8, two separate restrictions are placed in the'conduit L. The first of these is the nozzle 1", which is secured within a nipple r at the upper end of the condenser, and has its inner end tapered to a point and provided with restricted port T The nozzle r is preferably secured by a screw threaded engagement in the nipple T and in case of clogging at any time, may be readily removed for cleaning. The conduit L is connected to the nipple r by a detachable coupling r to permit of quickly disengaging the conduit. At the lower end of the conduit L is a second nozzle 3, which is preferably secured to the nipple 8 upon the arm 9 of the fitting L. The upper end of this nozzle is also tapered to a point and is provided with the restricted port 8 Both the nozzles 1" and s are of smaller external diameter than the conduits in which they are placed, so as to provide a well or chamber for the collection of sediment. Thus, the steam which enters the upper part of the condenser through the conduit J is obliged to pass first through the restricted port 7- into the nozzle 1', and after passing through the conduit L to again pass through the restrict-ed port 8 into the nozzle 5 before it finally enters the fitting L. In this fitting, when the valve L is seated the passage of the steam is again restricted by the port 1'. Thus, the carrying of sediment into the fitting L is effectually prevented, and when the valve L is closed, the restriction is so great as to prevent the passage of more than the water of condensation into the fit ting L. The fitting L is further provided with a passage 9 which connects the passage q with the conduit K leading to the oil cylinder of the pump. 9 is the port in the fitting L connecting the oil space therein above the transparent tube K with the conduit K and this port g is arranged below the level of the port 9 so that the'water of condensation passing through the latter into the conduit K will drain backward into the transparent tube K It will be understood from the above description that water is constantly supplied to the tube K from condensation'in the conduit L and its connections; and further than this water is filtered from impurities by passing through the various restrictions in the conduit L and valve L Should any minute particles of sediment pass through these restrictions, they are prevented from lodging in the fitting L by making the port Q3 larger than the restricted ports before mentioned. Where it is desired to supply heat as well as water of condensation,'the valve L is opened to provide a freer passage, with the consequence that hot water or steam is supplied. from the conduit L to the radiator tube L and will supply the necessary heat to the oil.

In lubricators of the type where the oil is propelled beyond the sight-feed by a jet of steam, the latter will always maintain the oil at relatively high temperature. .Vith my construction in which the propelling steam jet is omitted, it is desirable to heat the oil in the sight-feed as well as in the oil cup, and this is accomplished by passing the steam or hot water to the heater through the fitting L, which also contains the oil discharge conduit from the sight-feed. The same effect is produced in the sight-feed K on the opposite side of the cup A, and which furnishes oil to the air pump by extending the raidator tube L into a nipple Z of the fitting t, forming the upper portion of the sight-feed K. Thus, the fitting t is supplied with heat from the steam in the radiator L sutlicient to maintain the oil at proper temperature when it is discharged from the sight-feed K.

Air brake Zu-ha"2'cat0r.Tt has been stated that the sight-feed K is employed for feeding oil to the air brake steam cylinder. The amount of oil which is fed through this sight-feed is small in comparison with that fed through the sight feed K and delivered to the locomotive cylinders, and the con struction, as hereinafter described, is designed to produce a uniform feeding of this limited quantity of oil. As shown, M is a valve for controlling the feeding of the oil from the tube (Z to the oil discharge nozzle M in the sight-feed. The upper end of this sight-feed is formed by the fitting t as before described, and the oil is discharged therefrom into a conduit N, which connects to the conduit N leading from the steam box H to the air brake cylinder. The conduit N is provided with the usual valve or throttle N With certain constructions of the lubricator, the oil fed to the air brake is propelled by a steam jet having a source of supply independent of that controlled by the throttle valve N The result is that when the throt tle is closed, steam entering by the way of the jet will. at times, cause the continued operation of the pump. Vith my construction, this difiiculty is avoided by dispensing with the propelling steam jet, and the feeding of the oil is efiected by the following construction :t is achamber formed in the fitting i above the level of the discharge opening to the conduit N. O is a nozzle having a restricted passage 0 therein and located in the nipple i to which the conduit N is connected. This nozzle will permit the feeding therethrough of a maximum quantity of oil required for the steam cylinder of the air brake, but nevertheless forms a restriction, which prevents the free communication between the chamber 6 and the conduit N. During the operation of the air pump, at each reversal of the piston there occurs a pulsation, vaich momentarily increases the pressure of steam in the conduit N and this increased pressure is communicated to the steam in the conduit El and thence through the restricted passage 0 to the chamber 6 above the sight-feed. As soon as the pressure in the conduits Ii. It returns to normal, the over-pressure in the chamber 5 will cause the passage of steam through the restriction G, and if in the meantime one or more drops of oil have been fed through the sight-feed. these will be carried with the steam into the conduit N. Condensation of the steam within the chamber 3 will replenish the water in the sight-feed K, and any surplus in condensation will be fed with the oil through the restriction O at each pulsation of the steam. Cm. the other hand, the pressure of steam within the chamber t is constantly renewed at each pulsation, so that in effect the oil is propelled by a steam current without any connection to the source of supply other than through the di charge conduit itself.

For lubricating the cylinder of the pump 0, a conduit V is attached to the cup A, and a check valve TV is arranged in this conduit.

X is a valve fitting connected into the steam supply conduit J and serving to admit oil fed through the conduit V into the steam current.

The check valve VJ prevents any possibility of steam from the conduit V passing backward and into the cup A.

What I claim as my invention is 1. Tn a lubricator, the combination with an oil cup ofatubular heater extending into said oil cup, a conduit from a source of steam under pressure to said tubular heater. there being a restriction within said conduit, and a discharge port from said heater of greater capacity than said restriction, whereby the pressure within said heater is reduced.

4%. In a lubricator, the combination with an oil cup of a tubular heater therein, a sight-feed discharge conduit from said oil cup, there being a discharge port from said heater into said discharge conduit arranged to drain into said sight-feed, a conduit to said tubular heater from a source of steam under pressure, a valve for controlling said conduit, there being a restricted passage through said valve forming a constant drainage between said steam conduit and said heater.
